Cabbage aphid Brevicoryne brassicae (Linnaeus) and mustard aphid Lipaphis erysimi (Kaltenbach) are economic pests of major crucifer crops in Nepal, and insecticides are used commonly against these. To evaluate alternative safe management practices, a field experiment was conducted with cabbage at Dailekh, Nepal, with eight treatments. The results revealed that azadirachtin 1500 ppm led to minimum leaf damage and higher yield. Spinosad 45% SC treated plot and control plot showed the maximum incidence.
